The people who need the pledge the most are also the least likely to follow it when it's really put to the test. There was an interesting study done by the London School of Hygiene recently that found that people were much more likely to wash their hands if others were present in the bathroom, and if they were shamed into doing it by messages such as "is the person next to you washing with soap?" Of course, there are some people who will never wash their hands when they go to the bathroom. T I think most people really want to do the right thing, but there are lots of gray areas out there, especially when nobody is looking. Reaching people in that situation is what the vow is made for. Maybe a public promise to be ethical will be a gentle nudge to help them behave ethically. Those with really dirty hands are beyond the reach of any vow, and always will be.
